Usually, if a dog comes into a shelter with human aggresion issues, the dog is euthanized. Animal aggression issues can be overlooked by adopting to families as an only pet. But shelters assume to big of a liability to adopt out animals with any HA issues. Yiou said the letter stated that the dog "took a lady down" and "doesnt like males with facial hair" Thaat would be considered HA.
Either the shelter thought the letter to be bogus or overlooked it.
I would try it out. I mean you have already grown fond of the dog, it has yall as well, what other chances does it have after that letter is out now?
How old is it?
I would take it home, buy a crate and establish alpha immediatly. Crate train it, etc.
Good luck
